Hi,

I'm just wondering if anybody has any experience in using externals in ofxPd. I'm controlling a synth using an Xtion Pro Live sensor tracking my hands x, y, z coordinates. The data gets sent over UDP to Pd and controls my synth parameters. This works perfectly when I run my openFrameworks app and Pd-extended independently of one another.
However, when I call the patch in OF, I get nothing at all. I've tried sample sine wave patches as a sanity test to test the sound is working ok.
I've added mrpeach to my project as per the instructions here:

https://github.com/danomatika/ofxPd#adding-pure-data-external-libraries-to-ofxpd

He gives an example of using the zexy external in the instructions but the instructions don't transfer accurately to the mrpeach library.
I've tried using
mrpeach_setup;
udpreceive_setup();
unpackOSC_setup();
routeOSC_setup();

but have had no luck. Am I missing something really simple?
Hope someone can help.

Thanks

EDIT: I'm using XCode for development also

Thank you!
